2. Why is it important??? Communicate information and processes to causes it reaction in other parts of the body A network that relays messages back and forth Controlling different parts of your body like - breathing - digestion - sweating - shivering - many more! processing the nerve impulses

3. Components of the Nervous System Brian - cerebrum - cerebellum - brain stem - pituitary gland - hypothalamus Spinal Cord - runs along the dorsal side of your body - contains cell bodies & dendrites

4. Anatomy and Physiology Neuron is the functional unit We have 100 billion neurons in our BRAIN alone. Dendrites receives info from another cell & transmit the message to the cell body Cell body - nucleus - mitochondria Axon- conducts messages away from the cell body

6. The ANS Controls “vegetative” process & adaptation of stress Effects the smooth & cardiac muscles & Exocrine Glands Neurotransmitters Acetylcholine, Norepinephrine, & Dopamine Hormone: Epinephrine (EPI)

7. The PNS Digestion and other GI & urinary tract functions, and many more! “Targets” the activation of structures under PNS control All PNS activity is accomplished, physiologically It’s the peripheral nervous system

8. The SNS Mainly controls all cardiovascular functions- blood pressure & blood flow The sympathetic branch of ANS uses two neurotransmitters. ACH and norepinephrine plus a hormone: epinephrine to control its target. It’s sympathetic nervous system

9. The CNS Central (CNS) – The Brian and The Spinal Cord Sympathetic-is a branch of the autonomic nervous system along with the enteric nervous system and parasympathetic nervous system -active during times of stress Parasympathetic- serves as a slow heart rate, increase the intestinal & gland activity, & relaxes the sphincter muscles

10. Disease & Disorder common causes: aneurysm in the posterior parts of the circle of the willis, tumor, & occasion vessels Characterized by complete 3 rd neverpasy & associated with contralateral hemipelagia Due to damage to the structures at the base of the midbrain including the 3 rd cranial nerve Weber syndrome Huntington patients, ratio 40:1, normal people its 160:1 Leads to clementia and usually death. High thoughts of suicide Autosomally- inherited, people who have it fidget which develops into jery, choreiforn movements Huntington Disease Fact 3Fact 2Fact 1Name

11. Pictures of... Huntington Disease Weber Syndrome

12. Diseases & Disorders Likely to be loss of pain temperature sensation on the ipsilateral face Some cases, taste may be affected in the ipsilateral part of the tongue Difficulty in swallowing & hoarseness due to paralysis of the ipsilateral vocal cord Walsenbu rg Syndrome Looks as if in a coma, but you can move your eyes Lesions there render the individual, unable to speak & incapable of facial movements Due to stroke, tumor, or trauma to the ventral part of the costrel pons Locked-in syndrome Fact 3Fact 2Fact 1Name tongue

13. Pictures of… Locked-in Syndrome Walsenburg Syndrome

14. Drugs & Alcohol Alcohol is a centeral nervous system depressant Alcohol is a very small molecule and is soluble in “lipid” and water solutions because of these properties alocohol gets into the blood streamilery easily & also crosses the blood brian barrier
